This us from way back in the thread but again I agree with Stolen that we can't agree.
'For all of you, having a female biology is a necessary and sufficient condition of being a woman.
For trans people, and people who accept the validity of their experiences, a female biology is neither a necessary nor sufficientcondition of being a woman. Sex and gender are distinct.
The two positions can never be debated meaningfully between each other because we can’t agree on the logical starting premise.'
Absolutely. I do see why 'no debate' was ever proposed, because we might as well be arguing in different rooms.
To me, the main issue and the 'cis' issue is easily demonstrated like this. If we described a person of the male sex who transitions as a trans man (and logically from a linguistic point of view this makes more sense), and a person of the female sex who transitions as a trans woman, then obviously there is no need for anyone to identify themselves as cis. We have men and trans men, women and trans women. Women's spaces are for women.
That will never be accepted because transition isn't about logic, reason or objective reality. I accept that some things aren't about logic, reason or objective reality but it makes it a bit difficult to make any kind of legal or policy decision on it.
